[jira] [Updated] (SPARK-27630) Stage retry causes totalRunningTasks
calculation to be negative
[ https://issues.apache.org/jira/browse/SPARK-27630?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
dzcxzl updated SPARK-27630:
---------------------------
Description:
Track tasks separately for each stage attempt (instead of tracking by stage), and do NOT reset the numRunningTasks to 0 on StageCompleted
In the case of stage retry, the {{taskEnd}} event from the zombie stage sometimes makes the number of {{totalRunningTasks}} negative, which will causes the job to get stuck.
Similar problem also exists with {{stageIdToTaskIndices}} & {{stageIdToSpeculativeTaskIndices}}.
If it is a failed {{taskEnd}} event of the zombie stage, this will cause {{stageIdToTaskIndices}} or {{stageIdToSpeculativeTaskIndices}} to remove the task index of the active stage, and the number of {{totalPendingTasks}} will increase unexpectedly.
